"What are the words you love, or the phrases you wish would come back in fashion?"

Oh, there are many. I tend to use the occasional colorful phrase myself, due mostly to a childhood spent around people who use colorful phrases. So here are some that I use that I think everyone should:

Built like a brick shithouse.

Gone pear-shaped.

Crik (for creek)

Rig (for car or truck)

Batshit crazy.

Like a red-headed stepchild.

Busy as a one-legged man in an ass-kicking contest.

Others, that I don't use myself, at least not yet, but wish would come into fashion or back into fashion, are:

I still say "scared the tar out of [someone]". Also, "Heavier than a dead Okie" was one of my grandpa's favorites, 'cause that's where my grandma's family was from (and she was twice his size), tho it's harder to use without offending.
